【2025年10月版】macOS上のParallels上の Linux on Linux メモ【nested virtualization】

Posted at

はじめに

  • macOS上のParalles上の Linux で、qemuによる VM が動かせるということなのでやってみたメモ
  • 世にいう nested virtualization
  • Parallesは qmue で動いているそうなので、macOS 上で qemu 上の qemu という感じ

環境

  • MacbookPro M3 Max 64GB
  • macOS Sequoia 15.6.1
  • Parallels Desktop 26 fro Mac Pro Edition 26.1.1
  • Ubuntu 25.04
  • alpine standard 3.22.2

前提

Paralles 上に Ubuntu はすでにインストールされているとします。

手順

必要なパッケージをインストール

sudo apt update
sudo apt upgrade -y
sudo apt install qemu-system-aarch64 qemu-utils qemu-efi-aarch64

alpine linuxのダウンロード

使いたいバージョンをダウンロードしてください。大事なのは、aarch64 であること。

wget https://dl-cdn.alpinelinux.org/alpine/v3.22/releases/aarch64/alpine-standard-3.22.2-aarch64.iso

仮想ディスクの作成

qemu-img create -f qcow2 alpine.qcow2 2G

VMの起動（インストール時）

ヘッドレス／シリアル、4コア、I/O最適化、rng 追加、軽めCPU＆GICv2 で起動

  -device virtio-blk-pci,drive=vd,queue-size=1024 \
  -netdev user,id=n0 \
  -device virtio-net-pci,netdev=n0 \
  -object rng-random,filename=/dev/urandom,id=r0 \
  -device virtio-rng-pci,rng=r0 \
